Current Electricity: Practice Problem & Solution
3. The velocity of charge carriers of current (about $1 \text{ ampere}$) in a metal under normal conditions is of the order of (1991)
Solution Explained:
To solve this problem, we apply the core principles of Current Electricity. Understanding the underlying formula is key to arriving at the correct answer below:
The drift velocity of electrons in a typical metallic conductor under normal conditions is extremely small, typically on the order of $10^{-4} \text{ m/s}$ or a fraction of a $\text{mm/sec}$.
